Installation of Tekonsha Brake Controller Adapter

Junction BoxBrake-Control Adapter Port

This adapter plugs into the port that is built into the electric junction box beneath your vehicle's dash. The black box is located to the left of the steering column, just above the carpet. To plug in the adapter, first remove the cover on the box. The adapter plugs into the second slot from the left, on the top row.


To install your electric brake controller you need to connect the wiring of the controller to your vehicle. Certain manufacturers offer pre-wired options, typically known as tow packages, wherein these wires are run for you from the dash to the trailer connector on the back of your vehicle. Often, a brake controller wiring harness is included with your tow package. This harness plugs into a port beneath your dash and connects to the four wires of the brake controller. If, however, you have a brake controller with a plug in place of the four loose wires, you can use the Tekonsha adapter.


This adapter requires no hardwiring. It is designed to plug directly into your electric brake controller for the simplest installation possible. Because there are no wires to connect, installation is not permanent. You can unplug and remove your brake controller at any time and securely stow it away.

The hitch and controller was installed on a 2002 Chevy 2500HD. It took roughly 15 min to install the Tekonsha P3 Brake Controller, plug it in and program it. As far as the B&W Turnover Ball Hitch, I cut the hole in the bed and cut the heat shield out the day before while I was waiting for the hitch to arrive. The next day my parts arrived, I laid out all the parts to make sure everything was there and then started the install. I didn't want to cut the 1"x1/2" notch out of my fender well to get the angle iron in so I spent about 15 min. trying to get it up on top the frame from underneath the truck. A waste of time. Do like the instructions say, cut the notch and slide it straight across the top of the frame. It will save time and aggravation. After getting both braces in place I ran a piece of rope down thru the hole and pulled the hitch plate up into place and tied it off. I installed all the bolts finger tight, put the side plates on and tightened everything up. It looks nice and I saved myself a $435.00 installation fee. With out a lift and without taking my rear tires off it took about 3 1/2 hrs. to install by myself. The only thing I want to say to B&W is don't place the heavy metal hitch parts on the booklet with the packets of Lithium Grease in it, they bust as the picture shows. Last but not least, thank you Sherry for all your help with my order and getting it to me quick in such short notice. I really appreciated it.

Thank you so much for the excellent service. Noah was polite, patient and professional. His knowledge is parts, negotiating the website and the accounting process was impressive. After receiving the email confirmation I realized I hadn’t requested overnight shipping. Called back and spoke with Will who provided more excellent service. It was 6:50pm Wednesday so I expected the part to ship in the morning. Instead, Will was able to ship it immediately and I received it at 9am the next morning! That’s only 14 hours from order to my doorstep across the country! Well worth the extra cost. Big shoutout to UPS too! I will continue to recommend etrailer to everyone.

Wasn't quite as easy to install as expected. Needed an experienced mechanical eye hooked to a limber body to find the right plug in spot under the dash. Some debate on where on the dash to hang the brake box, but I went with where the holes already were. Those teeny screws are tricky to get in and really did require a 1/4" ratchet, my fingers couldn't do it. Simple procedure, but did need the right tools. Took about 25 minutes, but some of that was going for tools... YES I'D BUY IT AGAIN ! One detail I learned about after installation, NO FUSE in the truck for it to work off. Needs a 40 amp fuse, and I didn't have one. Something to consider if yer new brake ain't working... sorry I do not have photo ability, if someone comes along, I'll ask them to take a pic.

I usually don't say much about these things...this worked out of the box. I had an old electric brake module that wasn't in the catalog any more. It worked on the previous Chevy truck and I wanted to install it in other truck. The hookups were different and I figured it would take some reconfiguration. Not the case here...call before you buy is my advise. I never took pictures but all I needed was tie wraps for the extra cable I rolled up under the dash.

1999 Chevrolet Suburban

etrailer's instructions and videos are awesome. installation was a breeze UNTIL I needed to locate the brake signal wire (cold side of brake switch) on my 1999 suburban. What a pain. the switch is not very accessible let alone there are a ton of white wires under the dash --along with an alarm. Long story short, I found this in a GMC forum and it saved me big time: "Under the dash, next to the emergency brake is a black convenience box. At the bottom of the box is the letters GRN, next to that is the letters NAT with a small recessed box with two male spade connectors. The spade on the right goes to the brake switch. The wire from the brake controller is terminated there." Using the supplied probe tester I was able to verify this and finished up my installation. The Tekonsha Prodigy P3 controller works great.

The Tekonsha Prodigy P3 controller is still working great. I cant believe i didnt get one sooner. Easy to adjust on the fly and no issues at all.

Bought a new Primus IQ brake controller but it only came with a pigtail wiring that had to be spliced into my '01 Suburban. Ordered the direct fit wiring pigtail from etrailer.com and couldn't be more pleased! It literally took me less than 10 minutes to plug in the wiring and mount the brake controller. Excellent customer service and very fast shipping! The kind of shopping experience that causes repeat business. Thank you etrailer.com and customer rep Lexus for making everything so simple!

  • Parts Needed to Add 7 Way and Brake Controller to 1998 Chevrolet Truck
    To add a brake controller to your truck and swap out the connector with a 7 way you'll need a few parts. You'll need a working 4 pole flat trailer connector (which you said is currently on the truck), the Universal Installation Kit for Trailer Brake Controller # ETBC7 and a brake controller. The ETBC7 kit comes with all the connectors, breakers, and wires to get a brake controller installed and a 7 way at the back of your truck.

  • Brake Controller Installation on a 1999 Chevy C3500 Pickup Truck
    On a 1999 Chevy C3500 there will NOT be a brake controller port to plug in a brake controller. The brake controller has to be hardwired into the truck. Chevy did not start putting in a port until they switched the trucks from C or K to Silverado. Prior to that Silverado was just a trim option. I have included a link to a video that will help. It shows installation on a 1996 C/K series truck. Installation will be basically identical on your 1999 model. If your truck already has a 7-Way...

  • Installing a Brake Controller on a 2001 GMC Sierra 1500 with Factory 7-Way Trailer Connector
    Since your 2001 GMC Sierra came with a factory installed 7-way trailer connector, GM should have already completed the connections under the hood at the fuse box. However, we have found that GM did not complete the wiring on all trucks, even if they came with the factory trailer wiring.

  • Troubleshooting Brake Controller Installation in 2001 Chevrolet Silverado
    A common cause for a trailer brake circuit to activate at full power is a corrosion issue in the vehicle 7-way socket and/or the trailer plug. Corrosion can build-up inside a connector or on its contacts. When this happens two separate circuits, like the brake circuit and the 12V trailer power circuit, can become bridged together. This would result in the always-on 12V circuit bleeding into the brake circuit which would result in full power reaching the electric brakes all the time. The...
